Yoga, when you are in contact with Kṛṣṇa, that is the secret of success in this material world, working. Otherwise whatever you are doing, whatever you are working, it will produce some reaction and you will have to enjoy or suffer.
So here again, the same thing. Arjuna is thinking in terms, na caitad vidmaḥ kataran no garīyo (BG 2.6). So he is perplexed, "Which one, which side will be glorious? I shall stop fighting or not fighting?" In the next verses it will be seen... When you are in such perplexity, "what to do and what not to do," so in order to get right direction, you must approach the spiritual master. That will be done in the next verse. Arjuna will say that "I do not know. I am now perplexed. Although I know it is my duty as kṣatriya to fight, still I am hesitating. I am hesitating in my duty. So therefore I am perplexed. So Kṛṣṇa, therefore I submit to You."
